that isn't going to help matters since the 2 camera modules aren't the same. It will just lead to more issues.

If the wdrt did not help, then the camera must be having a physical problem - or the connections in the phone are loose

I think its not a hardware issue because the camera worked two three times. Once I open QR code scanner in the oprera browser camera started working. Then I took a picture after that again stopped.!!!
So firmware update will solve the issue?
